PTT-100 30 gram Solar Argos/GPS PTT

By spring of 2005, thanks to advances in both battery technology and power management of the GPS receiver, we were able to introduce our next generation of GPS PTT, the 30g solar Argos/GPS PTT. This PTT retained all the features of the larger GPS PTTs: 3D GPS locations, SiV™ technology to efficiently time transmission of data to satellites overhead, flexible duty cycle programming allowing up to five duty cycle seasons, repeating annually now in an even smaller lightweight package. Finally, biologists had the means to track birds in the 1kg range with GPS accuracy. As is true of all our solar PTTs, this PTT is microprocessor controlled and contains a battery. This makes data collection and transmission of data at night possible (in contrast to less sophisticated PTTs, which transmit only during daytime when the solar cells are exposed to light.)

Features

Microprocessor controlled battery charge management to allow the PTT to charge during the day and collect data and transmit at night

Temperature, Battery Voltage & Activity sensors

SiV™ transmission schedule optimized for the new JTA* schedule: the PTT transmits only at times when the likelihood of a satellite pass is greatest, and to contain Argos costs the PTT is programmed to transmit data during only 2 Argos billing quadrants on the transmission day

Programmable for up to 5 duty cycle seasons (defined by mm/dd calendar dates)

Programmed to take GPS fixes at user-specified hours, and to transmit at user specified intervals

GPS parsing software that outputs locations into easily manageable data files and kml maps that can be viewed in Google Earth™
